EGS Collab Experiment 2: Earth Model Datasets

May 29, 2022
747.89 MB
Publicly accessible
The EGS Collab Project performed a series of tests to increase the understanding the response of crystalline rock mass to stimulations and fluid circulation to efficiently implement enhanced geothermal systems (EGS) technologies. The EGS Collab team created two underground testbed...
